I just downloaded version 0.8.1 to my Mac (and you can stop me right there if this was a bad move and direct me to which version I should actually have downloaded) and under "Preferences" my only option is "Watch Folders." I am trying to connect Winamp to an external sound card and the instructions I find say to go to Preferences, but I'm not seeing any options for anything else, much less something to edit the sound card.
